WINDOW VENTILATOR 7 Filed June 18, 1956 INVENTOR- LZZ'MEJ H. WEBB ATTORNEY Patented June 21, 1938 --uNrTEo STATES PATENT oer-nee This invention relates to air-conditioning devices. It is particularly directed to a window ventilator, and the like articles.

An object of this invention is to provide a 5- window ventilator of the character described, having means to eliminate dust from air entering the room, while yet permitting a free flow of air therethrough.

A further object of this invention is to prol vide a ventilator of the character described, which may be readily mounted in position on a window frameand in which water is employed to remove dust from the air entering the room and to add moisture to the air for conditioning the la -same.

Still another object of this invention is to provide a neat, compact and durable window ventilater of the character described, which shall be relatively inexpensive to manufacture, easy to za -install and. clean, and withal, practical and efflcient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is an outside elevational view of a window frame provided with an air-conditioning window ventilator embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2--2 of Fig. 1;

Fig. 3 is a partial elevational inside view of the ventilator with parts broken away to show the interior construction; and

Fig. 4 is an elevational cross-sectional view of a portion of the window frame and windows slidably mounted therein, and illustrating a device forming part of my invention for preventing air 45 from flowing between the windows.

Referring now in detail to the drawing, Ill designates a window frame of usual construction and I I designates a window slidable therein. The

frame I0 comprises a bottom portion I3 and side portions I4. Mounted within the frame Ill and below the window II is an air-conditioning window ventilator I5 embodying the invention.

The ventilator I5 may be made of wood, galvanized iron or other suitable sheet metal. The

55- 'same comprises a case I6 and a removable cover I1 for said case. The case I6 hasa flat bottom wall I9 adapted to rest on the bottom of the frame I3. Extending upwardly from the front of the bottom wall I9 is a vertical front wall 60 and extending upwardly from the rear of said 7 Claims. (01. 98-100) bottom wall is a rear vertical wall 2 I. The rear wall 2| extends to a higher level than the wall 20 and terminates in a top edge 2 Ia. Extending rearwardly from the top of the front wall 20 is a top wall 22, terminating short of the wall 2! and provided with a downwardly extending flange 23. The front wall 20 has, adjacent the top thereof, a plurality of spaced openings or perforations for the purposes hereinafter appearing. The rear wall 2| has, adjacent the top thereof, a plurality of spaced openings or perforations 26, the purpose of which will be explained hereinafter. Said front wall'is also provided at a bottom corner thereof with a removable screw plug 27 for draining water within the case I6, as will appear hereinafter.

The case 16 further comprises end walls 29' to close the ends of the case. The end walls 29 interconnect the top wall 22 with the bottom wall I9 and each has a front vertical edge 30 extending above the top wall 22 and a top horizontal edge 3| somewhat below the level of the top edge Zia.

The cover I! has a top wall contacting the edges 3| of the end walls 29 and a folded-over channel 36 adapted-to frictionally engage the upper edge Zla of the rear wall 2|. Extending downwardly from the wall 35 is a vertical wall 38 contacting the edges 3!] and projecting into the case I6. The lower end of the wall 38 projects below the flange 23 and serves as a baffle for air entering the openings 26 and passing through the case to the openings 25. The portion of the wall 38 which extends below the top. wall 22 of the case I6, is preferably somewhat narrowed to permit insertion thereof into the case.

As shown in Fig. 2 of the drawing, the bottom of the window I4 contacts the wall 35 of the cover II, so that air entering the room must pass through the ventilator. Water may be placed into the case I6, the level of the water being below the bottom edge of the wall 38 of the cover [1.

It will now be understood that air entering the room must first pass through the openings 26 beneath the baffle 38 and through the openings 25 as indicated by the arrows in Fig. 2 of the drawing. The air while passing through the ventilator is cooled and'cleaned of dust by the water and gathers moisture to condition the air. The water may be removed from the ventilator by unscrewing theplug 2'I.

It will be noted that the front window II is moved down into contact with the top of the ventilator I5 as shown in Fig. 2 of the drawing. Means is also provided to prevent air from flowing between the front and rear windows and thus entering the room, whereby air can only enter the room through the ventilator. When the front window is in contact with the top of the ventibetween the windows. Any air entering the room through the frame I0 must therefore pass through the ventilator I5.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to sing is to be interpreted as illustrative and not meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made ,in the embodiment above set forth, it is to be understood thatall matter herein set forth or shown in the accompanying drawin a. limiting sense.
